主题：[求助] cmd 同时使用

老师，这两Cmd 可同时用吗 ？会损坏数据库吗？

Dim cmd As new SQLCommand
    cmd.C
    cmd.CommandText = "upd ate ICBOMChild set FEntrySelfZ0142 = a.FItemID from ICBOM As a where a.FInterID = ICBOMChild.FInterID And (a.FItemID <> ICBOMChild.FEntrySelfZ0142 or ICBOMChild.FEntrySelfZ0142 is null)"
    cmd.CommandText = "upd ate ICBOMChild set FEntrySelfZ0142 = null from ICBOM as a where a.FInterID = ICBOMChild.FInterID and FUseStatus <> 1072"
cmd.ExecuteNonQuery
